This Recommendation / International Standard provides the framework for the realization as an OSI application context of the abstracts concepts of operation package and association contract defined in ITU-T Rec. X.880 / ISO/IEC 13712-1. Such an application context is described in terms of a collection of application service elements, in particular the Remote Operations Application Service Element (ROSE), which drives the general purpose protocol for invoking and reporting the returns of arbitrary operations.
The terms, definitions, and mechanisms defined in ITU-T Rec. X.880 / ISO/IEC 13712-1 apply here and are specialized for an OSI realization as specified in this Recommendation / International Standard. This Recommendation / International Standard focuses on the services provided by ROSE, and the way ROSE is used. The ROSE services are provided by the use of the ROSE protocol (specified in a companion Recommendation / International Standard, ITU-T Rec. X.882 / ISO/IEC 13712-3), in conjunction with the Association Control Service Element (ACSE) services (ITU-T Rec. X.217 / ISO 8649) and the ACSE protocol (ITU-T Rec. X.227 / ISO 8650), and, optionally, the Reliable Transfer Service Element (RTSE) services (ITU-T Rec. X.218 / ISO/IEC 9066-1) and the RTSE protocol (ITU-T Rec. X.228 / ISO/IEC 9066-2), and the Presentation service (ITU-T Rec. X.216 / ISO/IEC 8822).
No requirement is made for conformance to this Recommendation / International Standard.
